TO ALL WHOM IT MAY OONCERN:

Be it `known that I, ROBERT BAXTER, of French Camp, in the county of San Joaquin, and State ot' California, have invented a new and' useful Machine for Sowing Grain, and called Baxters Grain-Sower, to be used -in connection with gang-ploughs or cultivators; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a front elevation of the grain-sewer, with the outside piece ofthe front part removed, the uppe front piece O and middle piece F remaining, thus showing the inside ofthe lower part of the seed-box, (to wit, below F the rod B, and its prongs C, and the ironplates D and E, on the bottom and at the front side of the box also appear the elbow G and pitman H, by which the power from the plough-wheel K is communicated to the rod B, giving it, with its prongs C, a lateral motion when the plough is in operation, the ends ofthe prongs being turned towards the centre of the box, and passing back and forth over the holes in the plates, the object` being to keep the holes clear, and to secure a steady flow of grain thereby.

Figure 2. D shows the upper plate, which is let into the bottom of the box, so that the top part is level with the same, being (4g) four and one-halt' inches wide, and (c) one-sixteentl1 of an inch thick; also are shown the ends of the prongs C, turned towards the centre of the box.

Figure 3. E shows the lower iron plate, in which, as in the upper plate, there are small holes, three-fourths of an inch in diameter, the same corresponding in. size and distance with those in the upper plate. This plate, being a little shorter than the upper plate, is capable ofte. lateral motion, the same being eifected by means of a small handle, P, (iig. 1) attached to the lower plate, thus' regulating the How of the grain.

Figure 4 presents an end view of the seed-box, and its connection with the plough; also shows the elbow G, pitman H, and iron clasp or elbow Q, (which clasps the corner of the box,) in which are set two eyesV V, which receive the ends of a gudgeon projecting either way from the elbow, thus forming a. pivot, on which the elbow G- works.

Figure 5 shows a cross-section of the box, including the rod B, its prongs C, the iron plates D and E, and holes therein; also S, apiece of sheet iron, which is screwed to the bottom of the box just behind the holes,

and on which the grain falls, and by which it is scattered, the same tapering from thebox, and being two and a half inches wide at the box, (1) one inch wide at the lower end, and (5) ve inches long.

' In iig. 1, L represents a cross-beam, in which the boxl rests when used with Baxters gang-plough, the same being secured by bolts through the bottom of the box. N represents the end of the main beam, and M otherA cross-beams of said plough, to which the drawing-gear is attached.. I, the irons connecting the wheel with the plough, and K the wheel. I

The seed-box and machinery connecting it with plough-wheel can be easily used with any gang-plough.

ItI is constructed of inch boards, (lighter may be used,) the end pieces being of irregular form, as by fig. L appears. The top part or cover of the box A is (10) ten inches in width, and secured to the back part by a hinge, and designed to be level when in position. The back'part (as appears by X, cross-section, iig. 5) forms un acute angle with the top part, slanting forward, and being (8) eight inches in width or height. With the back part, the bottom pieee`(as appears by cross-section 7,.ig. 5) forms an obtuse angle, slanting forward to front piece, and being (8) eight inches wide. The front part is composed of three pieces, (es appear in' O, F, and E, cross-sections, iig. 5,) being (10) ten inches high, and its generalpositi'on or line at right angles with top part or cover. The top piece O (of front side of box) is about (5) tive inches wide, and is set into the end pieces, und back of thc front edge thereof, about (1%) one and one'halt` inch, leaving a shoulder at the upperfront corners of the end pieces. (See Z, fig. 4.) t

To thc bottom part of piece O, (iig. 1 or 5,) and at right angles with it, is attached the piece F, (fig. 1 or 5,) (3) three inches in width, one-half of same (inch and one-half) extending back and theV other in front of piece O, (see F, tig. 5,) and even with the front edge of the end pieces R R, iig. 1.' In this piece F there are grooves, through which the prongs C pass to the bottom of the box, of sucient width to allow a horizontal motion of the prongs over the holes in the plate D.

To the end pieces R R, und the middle pieces F, F, and S, and the bottom part, is attached the third piece,

or outside front piece, which is a plain board, of proper size te cover the front of the box within two inches of the top thereof, leaving a space of little over an inch between the piece O and the outside front piece E', (see iig. 5,) in which is placed the rod B, which is kept in place by, and playsback and forth in, grooves cut in the end pieces, said grooves being protected by nail-plate, screwed't/o the end of the box, in which there are like grooves. Said rod B is of iron, and one-quarter) of' an inch thick, and one-fourth of aninch wide, and

long enough to connect with the elbow Gr, and allow a horizontal motion suiicient to carry the prongs back and forth over the holes in the plate D.

The prongs C ofthe rod are three-eighths by three-sixteenths ot' an inch, and at the end in two parts, C, fig. 2.

The rod B is operated by the wheel, through the elbow Gr, 'in the upper arm of which there is a groove, into which is received the end of the rod B, the rod being cut down on each side thereof, so as to fit into the groove ofthe elbow, and have two shoulders on either side of same, against which the'elbow works. The other arm of thc elbow Gr is connected, by means of a common pitman, with a pin on the wheel, about one and onehalt` inch from the centre thereof, the wheel thus furnishing th-e moving power for the rod B. i

It will be seen, by examination-of gs. 1 and 5, that the ends of the prongs are within the box, and close to the front side thereof, the rod and that part of the prongs C C above F, fig. 1, being outside of the box proper. p

The plates D and E, (gs. 2 and 8,) placed on the inside and close to the front part ofthe box, are let into -tbe bottom piece D equal to its thickness, and E underneath D equal to its thickness, in a. separate groove.

The upper plate D is secured in place by the front edge being let into the front piece, and screwed at its back edge to the bottom of the box. The lower plate E is shorter than the bex, so as to admit of an end motion suicient entirely to shut ofi' the {iow of grain. Both plates have holes of three-fourths inch in diameter in them, and corresponding with each other. Directly underneath the holes, in the upper plate D, are corre spending holes in the bottom part of box, through which. the grain escapes, the flow of grain being controlled by moving the lower plate E, which is done by neans of a handle thereto attached,` (P, iig. 1.)

The wheel of the plough with which this seed-box is used should not be over (15) fifteen inch'es in diameter.

The length of the box is controlled bythe size of the gang. The holes through which the grain escapes should each be on a. line with land-side of the standards, and the pieces of sheet iron on which the grain falls should be turned or twisted towards the furrows. There should be one hole to every standardt' p The object of the middle piece of the front part of the box'(E, fig. 1) extending'back into the interior o bo'x is to relieve the prongs C of any over weight from the grain when the box is full.

What I claim as novel, and for which I ask Letters Patent, is

1. The seed-box, constructed as described, and provided with a rod and prongs, so located that a part ot the severalprongs only is in the box, and that at the front side thereof, as and for the purpose described.

2. The elbow-lever, operated by a pin on the plough-wheel, and operating the rod with its prongs, in com# bination with said rod, in the manner and forvthe object set forth.
